Abstract
In a method for detection of defective ultrasonic transducers in an in ultrasonic sensing device, an ultrasonic signal is generated at an ultrasonic sensing device comprising a plurality of ultrasonic transducers. A reflected ultrasonic signal corresponding to the ultrasonic signal is received at at least one ultrasonic transducer of the plurality of ultrasonic transducers. It is determined whether performance the at least one ultrasonic transducer is degraded based at least in part on the reflected ultrasonic signal.
